That is the question. Always looking for more power out of motor as it is tow rig. Just curious if anyone has experience with either of this. I know running both is 99% out of the question, but figured it is worth asking. Are either of these any good? I have already free'd up the intake and throttle body and exhaust, plus I am going to be installing the the 19#er's and high pressure FPR. I have 93 4 liter with manual tranny, and am debating about which one I should run. I am going to e-mail both companies to see if they will even be compatable with the different FPR and injectors, but thought I would see if anyone here has actual experience with them.
